A new experiment was created for the physical chemistry course at Ball State University using a bomb calorimeter to measure the enthalpy of combustion of sucralose. The motivation behind this experiment was to alleviate misconceptions about zero-calorie foods and their enthalpies of combustion. The enthalpy of combustion of sucralose was determined to be –14.9 ± 0.9 kJ mol-1 at 298 K, which is consistent with typical carbohydrates.
